In recent years, many frog species around the world have declined in numbers or even gone extinct due to changes in their environment. These population declines and extinctions have serious consequences for the ecosystems in which frogs live; for example, frogs help play a role in protecting humans by eating disease-carrying insects. Several methods have been proposed to solve the problem of declining frog populations.
First, frogs are being harmed by pesticides, which are chemicals used to prevent insects from damaging farm crops such as corn and sugarcane. Pesticides often spread from farmland into neighboring frog habitats. Once pesticides enter a frog’s body, they attack the nervous system, leading to severe breathing problems. If laws prohibited the farmers from using harmful pesticides near sensitive frog populations, it would significantly reduce the harm pesticides cause to frogs.
A second major factor in frog population decline is a fungus that has spread around the world with deadly effect. The fungus causes thickening of the skin, and since frogs use their skin to absorb water, infected frogs die of dehydration. Recently, researchers have discovered several ways to treat or prevent infection, including antifungal medication and treatments that kill the fungus with heat. Those treatments, if applied on a large scale, would protect sensitive frog populations from infection.
Third, in a great many cases, frog populations are in decline simply because their natural habitats are threatened. Since most frog species lay their eggs in water, they are dependent on water and wetland habitats. Many such habitats are threatened by human activities, including excessive water use or the draining of wetlands to make them suitable for development. If key water habitats such as lakes and marshes were better protected from excessive water use and development, many frog species would recover.
The professor disagrees with the notion in the text about three methods to resolve the problem of reducing frog populations. She brings several explanations to support her idea.
First, the lecturer specifies that prohibiting farmers from using pesticide will not be a fair plan because some farmers may lose great deal of their crops. On the other hand, the farmers who they can use pesticides may have many crops in comparison with other farmers. In contrast, the reading claims that by inhibiting farmers from using pesticides we will be able to increase the populations of frogs because pesticides are harmful for frogs.
Second, the speaker states that treatments is not a good method since we should treat each frog individually. Hence, that would be a difficult proposal. Besides, the professor says that we should treat the next generation of frogs again because by treatment we are not able to treat offspring and the infection may transfer to the next generation. However, according to the passage, by treatments we can prevent infection. Therefore, we are able to improve the frog populations.
Finally, the instructor hints that humans do not have any impacts on the wetland habitat of frogs . As a matter of fact, the global warming has negative effects on the wetland habitat and it may caused to extinct of entire species on the wetland. In addition, we are not able to protect the change that happened by global warming in the wetland. On the other hand, according to the reading, humans activities led to the reduction of frogs populations because human activities destroyed habitat of frogs. Besides, the author of the text believes that we can recover the frogs by protecting the lake with excessive water.
